[Digikam-users] Sharpening in 1.0.0 SVN

[Andi Clemens]

Fixed with commit #987077.
Again: the label was wrong for the old blur method. So what you set in this 
dialog was never a radius, but a diameter.
With this commit you can use double values for the radius. Therefore you need 
to bisect the old value you used in 0.10, to achieve the same results.
